Abstract:
Population studies of Kepler's multiplanet systems have revealed a
surprising degree of structure in their underlying architectures.
Information from a detected transiting planet can be combined with a
population model to make predictions about the presence and properties
of additional planets in the system. Using a statistical model for the
distribution of planetary systems, we compute the conditional
occurrence of planets as a function of the period and radius of
Kepler-detectable planets. About half (0.52±0.03) of the time, the
detected planet is not the planet with the largest semi-amplitude (K)
in the system, so efforts to measure the mass of the transiting planet
with radial velocity (RV) follow up will have to contend with
additional planetary signals in the data. We simulate RV observations
to show that assuming a single-planet model to measure the K of the
transiting planet often requires significantly more observations than
in the ideal case with no additional planets, due to systematic errors
from unseen planet companions. Our results show that planets around 10
day periods with K close to the single-measurement RV precision
(σ1,obs) typically require ∼100 observations to measure their K
to within 20% error. For a next generation RV instrument achieving
σ1,obs =10cm/s, about ∼200 (600) observations are needed to
measure the K of a transiting Venus in a Kepler-like system to better
than 20% (10%) error, which is ∼2.3 times as many as would be
necessary for a Venus without any planetary companions.
